Inflammatory fibroid polyps in digestive tract:a clinical and pathological analysis of 14 cases / 临床与实验病理学杂志

ABSTRACT

Purpose To investigate the clinical and pathological features of inflammatory fibroid polyps ( IFPs) and to discuss its diag-nosis, differential diagnosis and treatment. Methods Clinicopathological data of 14 cases of IFPs were collected and analyzed retro-spectively. Results Most of the 14 cases were found to have submucosal polyps of the digestive tract protruding growing into the cavi-ty. Perivascular onion skinning which formed by spindle fibrocytes around vascular proliferation and eosinophilic inflammatory infiltrates were present as the characteristic feature of lesions. ABC results demonstrated that the lesions showed fibroblastic, myofibroblastic and dendritic cell signs. Conclusions IFPs are rare, benign tumors that can arise throughout the digestive tract, with unique histological changes in pathology. Surgical excision or endoscopic removal is the main treatment.
